Derivative of the Sine Function
part 1: write one page about a place where trigonometric iddentitiesare used in real life. include the identity where it is and where it' found.
part 2: derive ane xpression for the difference quotient when the function is sin(x) and when it's cos(x). show all steps in derivation
part 3: find a real world situation where sum-to product identity is used for something other than solving calculus problems
would love any help on any part of this...gimme a link or maybe the answer in part 2's case.......thanks
I always wonder what is meant by "real life" in questions like this!
The "difference quotient" for function f(x) is so that would just be and . It looks like that is all you need here.
For the other two questions, I would suggest you look to surveying problems.
